A problem which sometimes occurs is that the plug of bottom material which enters the interior of a suction anchor during installation of the anchor may disturb the pumping process, since the reduced pressure may cause expansion of the said plug, the result being that the anchor does not reach the desired depth in the waterbottom. According to the invention this problem is solved by removing the upper part of said plug from said interior by introducing water into said interior, forming a mixture of bottom particles and water and removing the mixture formed from the said interior. |
